Uran Asas BENJAMIN CRABTREE CALDERWOOD, V0F VALLEY- FALLS, RHODE ISLAND, ASSIGNOR T0 PRICE-CAMPBELL COTTON PICKER CORPORATION, 0F NEW YORK, N. Y., A GOR- PORATION V0F DELAWARE.

To all whom it may concern.'

Be it known that BENJAMIN CALDERwooD, a citizen of the United States residing at Valley Falls, in the county of CRABTREE Providence and State of Rhode Island, havev inventedV certain new 'and useful Improvements in Lubricating Devices, of which thev let end covered over with a piece of cottonv wicking, herein described and hereafter referred to as an oil retainer. rllhe oil 1s conveyed to the carriers by the action of oil.

gatherers, which consist of short pieces of tubing with holes drilled in the shell, and forced into the extreme upper end of the spiral shafts in the carriers, passing in succession under the retainer as the carriersv revolve around-the drum center, each gatherer wiping off a quantity of oil, which finds its way to the interior of the carriers through the holes provided.

The objects of my invention are: first, to insure constant, plentiful and equal lubrication to each and every carrier in the cotton-picking machine', and second, to provide means for sufiiciently lubricating the various inolosed parts in the carriers, as well as the sliding clutch and Vcombined pinion and clutch at the upper end of the spiral shafts.

I attain these objects in the manner illustrated in the accompanying drawings, in which- VwFigure lis a section through the top drum plate and covers, the oil retainer, carriers, and upper and lower carrier wheels,

and illustrates the path of the lubricant from the time of leaving the sight feed oil cups until it leaves the carrier. Figs. '2, 3 and et show details.

Referring to the drawings, 1 is the sight feed oil cup, 2 the duc-t which leads the lubricant from the reservoir to an oil retainer 3, 4 the wick, which absorbs the lu'- bricant, and 5 the tubular, wiping oil gatherer at the eXtreme upper end of the spiral shaft in the carrier.

6 is the spiral gear-shaft, the greater por- Specication of Letters Patent LUBRICA'JIINGl DEVICE.

ytion of which is inclosed in and rotates in the carrier, 7 the spiral gear, integral with the shaft 6, and 8 the carriers. v

9 are the combined pinions and finger sockets, meshing with the spiral gears 7, and which, in rotating, force the lubricant into their respective bearings, and 10 the bottom carrier pivots, which serve the double function of acting as a step for the spiral shaft 6, and a pivot for the carriers.

11 is a fixed circular gear ring, around vwhich revolve the carriers and their respective mechanisms, 12 Vthe clutch tension springs, and 13 the clutches, which also derive their lubricant from the oil retainer 2,v via the oil gatherers 5.

14 are the cam arms, 15 the top carrier wheel, 16 a picking finger, 17 the main translating cam, 18 the top drum plate, whichA supports the entire drum mechanism, and'19 and 2O are gear covers over the top drum plate.

2l is the lower carrier wheel, 22 a hardened steel stop ring upon which rest the carriers 8. 23 are the dowels which secure the pivot studs 10 to the carriers 8; 24: the screws which hold the drum centers to the top drum plate; V25 a lock nut for the oil retainer 3; and 26 a hole drilled through the pivot stud 10 for the purpose of allowing the excess lubricant t0 escape.

The oil gatherer 5 is a tube fiXed projectingly in the upper end of the hollow shaft 6. This tube where it projects from the shaft has its wall perforated at 5a. The upper end of the hollow shaft is provided at X with an annular oil gathering groove shown formed by anV inward bevel of the upper endwall of the sleevermember of the upper retainer 12a for the spring 12. The groove X catches and diverts oil dripping from the wick into the tubular wiper 5 whence it runs downwardly through the chamber of the hollow shaft'G. `The upper open end of the wiper or gatherer 5au contacts gently with the under endv of the wick and during rotation of the shaft 6 and the wiper, the latter gathers 'oil from the wick which can be adjusted endwise by the lock-nut 25. In cotton picking machines it is of great importance to so control the lubricant that What I claim isz- In a Cotton picker the combination of an oil Wick with a hollow carrier shaft provided with an open ended tubularl oilgatherer operating adjacent the wick end, the tubular oil-gathererl having an exposed perforated side wall below its end opposed to the Wick; and an annularly grooved means opposed to the wick and surrounding the perforated Wall7 whereby oil coming from the Wick exteioi'ly of the oil gatherei` is guided into the chamber of the oil gatherer. In testimony whereofl I have hereunto set my hand in the presence of two subscribing Witnesses, this 25th day of April, 1913.
